She's Jokerette only in the sense that she fell into chemicals that made her hair and skin funny, and she went crazy. She's still Harley, and after 20 or so minutes people will get over that just like they all got over her new outfit.
Actually, I'm STILL not over the new outfit. I'm being petty, I know, but all I see when I look at the new Harley is '90s comics.
"Clown hats aren't cool. Let's give her colored hair instead, cause that's more badass."
"Now she has knives and stuff, cause mallets and joke weapons are for sissies."
"And then let's put her in a skimpy corset cause.... cause BOOBS!!!"
I agree that she's more in line with the "evil clown" archetype now, but that's part of why I'm disappointed. "Evil clowns" aren't interesting. They've been done before and better. Harley was always different than that type of character. I liked that out of costume she looked normal and adorable. It made it all the more intriguing whenever they'd peek under the hood and remind you that, yeah, this chick's pretty friggin' nuts.
The new Harley just seems too much like every other "scary clown" character out there. And that's one of the saddest things I can think of for such a unique and interesting character.
